The White House says President Barack Obama won't include cost-cutting changes to Social Security in his proposal to reduce long-term deficits, a signal that he could move away from some other cuts in benefit programs that he was ready to support during failed summer negotiations with House Speaker John Boehner.

"As the president has consistently said, he does not believe that Social Security is a driver of our near and medium term deficits," White House spokeswoman Amy Brundage said Thursday. "He believes that both parties need to work together on a parallel track to strengthen Social Security for future generations rather than taking a piecemeal approach as part of a deficit reduction plan."

In July, during talks with Boehner over raising the nation's borrowing limit, the White House had proposed reducing cost-of-living adjustments for most Social Security recipients, a proposal that met stiff Democratic resistance.

Senior administration officials say the negotiations with Boehner took place under deadline pressure to produce a congressional deal that could swiftly win enough Democratic and Republican votes to avoid a damaging government default. That deal collapsed and Congress raised the debt ceiling only after lawmakers and Obama agreed to cut $1 trillion in spending and aim for $1.5 trillion more in deficit reduction by the end of this year.

Without a looming default, officials say Obama is now free to present a deficit cutting plan on his terms. In announcing his proposal Monday, Obama is expected to provide a deficit reduction framework that picks up where he left off last April, when he delivered a speech at George Washington University that set a goal of reducing deficits by $4 trillion over 12 years.

That speech specifically left Social Security out of any cost-cutting formula. While aging baby boomers will put a strain on the government retirement program, which is financed through payroll taxes, economists point to health care as the main driver behind the nation's growing debt.

In his April speech, Obama proposed reducing the costs of Medicare and Medicaid, the health care program for the poor, by $340 billion by 2021, in part by enforcing slower growth of Medicare costs and containing payments to health care providers. In talks with Boehner this summer, the White House identified $250 billion in Medicare spending reductions and $110 billion in Medicaid reductions.

In those negotiations, Obama had been willing to consider raising the eligibility age for Medicare gradually from 65 to 67 over a period of years and requiring that wealthier Medicare beneficiaries pay more for premiums and co-pays. Many Democrats, however, objected to an increase in the age for beneficiaries.

A document circulated this month by Democratic aides to the House Ways and Means Committee lists a number of options for health care savings, but calls raising the eligibility age "a radical departure from current policy."

"It isn't the panacea that some people talk about, where it doesn't hurt anybody and it's just the natural order of things," said economist Marilyn Moon, a former trustee who helped oversee Medicare and Social Security finances.

If Obama's new health care law isn't overturned, guaranteed private health insurance would be available to middle-class early retirees starting in 2014. But it wouldn't be cheap. The nonpartisan Kaiser Family Foundation estimates the annual premium for someone in their 60s would be more than $10,000, not counting any government subsidies that person might be entitled to.

A Kaiser analysis this summer found that the savings to federal taxpayers would mean higher costs for others. Two-thirds of 65- and 66-year-olds would pay more for their new coverage than they would have under Medicare.

The negotiations with Boehner also included $1 trillion in deficit reduction achieved through a reduced military role in Iraq and Afghanistan. Republicans have objected to using those savings for deficit reduction, but senior administration officials point out that Boehner had agreed to it and that a House Republican budget also counted on those savings.

That alone could go a long way toward meeting the president's debt trimming goal, but it could depend on how a congressional supercommittee chooses to measure long-term deficits.

The president's goal of at least $2 trillion in deficit reduction exceeds the $1.5 trillion that the supercommittee has been assigned to identify. Obama has called for the higher figure to pay for the $447 billion jobs bill that he sent to Congress this week.

Obama has proposed that the bill be paid with nearly $450 billion in tax revenue, achieved by limiting deductions for wealthier taxpayers, closing corporate loopholes and eliminating tax subsidies to oil and gas companies.
